“…On the other hand, we have previously reported that those with low serotonin 1A BP F —the opposite of what we found here—have greater aggression, 59 found in some studies to be linked to more lethal suicidal behavior. 60,61 Our sample had relatively low aggression (mean score, 18.5), perhaps indicating that aggression was not a key driver of suicidal behavior for this study population.…”

“…Several studies have highlighted the importance of aggression and related concepts to SSAs. Doihara et al ( 30 ) studied the aggression dimension in 55 MSSA attempters in a hospital’s emergency room, and compared them with a control group of 71 healthy individuals. It was found that aggression and hostility scores were significantly higher in the SSA attempters when compared with controls.…”

Serious Suicide Attempts: Systematic Review of Psychological Risk Factors

BackgroundOne of the main obstacles in studying suicide risk factors is the difference between cases in which the individual died by suicide and those in which the individual engaged in suicidal behavior. A promising strategy that overcomes this obstacle is the study of survivors of serious suicide attempt (SSA), i.e., an attempt that would have been lethal had it not been for the provision of rapid and effective emergency treatment. Serious suicide attempters are epidemiologically very much like those who died by suicide, and thus may serve as valid proxies for studying suicides. This paper aims to define the specific risk factors for SSAs by conducting a qualitative data synthesis of existing studies.MethodsFollowing Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, we conducted a systematic search of the literature in PubMed, ProQuest, and Psychlit electronic research-literature databases. Search terms were “serious” “OR” “near lethal,” combined with the Boolean “AND” operator with “suicide*.” In addition, we performed a manual search on Google Scholar for further studies not yet identified.ResultsThe preliminary search identified 683 citations. A total of 39 research reports that met the predefined criteria were analyzed. Mental pain, communication difficulties, decision-making impulsivity, and aggression, as well as several demographic variables, were found to be major risk factors for SSAs.LimitationsWe found a variability of definitions for SSA that hamper the ability to draw a model for the risk factors and processes that facilitate it. Moreover, the role of suicide intent and planning in SSA is still unclear. Further studies should aim to clarify and refine the concepts and measures of SSA, thereby enabling more specific and concrete modeling of the psychological element in its formation.ConclusionSSA is a distinguishable phenomenon that needs to be addressed specifically within the scope of suicidal behavior. Interpersonal problems, as well as impulsivity and aggression, seem to facilitate SSA when mental pain serves as a secondary factor. Healthcare professionals should be aware of SSA, and familiar with its specific risk factors. Moreover, psychological and suicidal risk assessment should include a designated evaluation of these risk factors as part of intervention and prevention models for SSA.

“…One of them compared medically serious suicide attempters (MSSAs) to healthy controls. Trait aggression was significantly higher in the MSA group, 53 however, that study did not include a non-medically serious suicide attempters (NMSSAs) control group. In another study designated to look for differences among those with specific psychiatric pathologies, personality-disordered individuals, particularly those who are more impulsive and aggressive and who have a co-morbid depressive disorder were found to have a higher risk for more frequent and more medically-severe suicidal behavior in comparison to individuals with Major Depressive Disorder (MDD) or Bipolar Depression (BD) alone.…”

Suicide and Suicidal Behavior

Suicidal behavior is a major public health problem. As it has for decades, suicide remains one of the leading causes of death in the western world. This paper reviews the literature and the latest developments on the research and knowledge of suicide behavior and death from suicide. The keywords: suicide, psychopathology, mental pain, impulsivity, aggression and communication difficulties were entered into databases: PubMed, PsychLit and ProQuest. Significant articles were scrutinized for relevant information. According to WHO estimates for the year 2020, approximately 1.53 million people will die from suicide, and ten to 20 times more people will attempt suicide worldwide. These estimates represent on average one death every 20 seconds and one attempt every one to two seconds. Although of low predictive value, the presence of psychopathology is probably the single most important predictor of suicide. Accordingly, approximately 90 percent of suicide cases meet criteria for a psychiatric disorder, particularly major depression, substance use disorders, cluster B personality disorders and schizophrenia. Other more transient factors that reflect an imminent risk of suicide crisis and therefore require immediate intervention include unbearable mental pain and related experiences of depression and hopelessness. Problems with help-seeking, social communication and self-disclosure also pose a suicide risk, as do personality traits of aggression and impulsivity. All these factors are highly correlated with suicidal behavior across psychiatric samples and nosological borders. Although suicidal behavior has been well studied, empirically and clinically, the definition of the different subtypes and phenotypes of suicidal behaviors and mechanisms underlying some of the risk factors (such as aggression, impulsivity, suicide intent) remain unclear. Reducing the increasing trend of suicide rates among the most vulnerable populations will require further research. Hopefully this review will contribute to the understanding of this phenomenon and to the development of preventive initiatives
